Hello, so recently I installed GPU Tweak and I accidentally clicked the ‘Default’ button on professional view and it changed a lot of things on my GPU which caused it to get black boxes and got a black screen of course I started panicking and held the power button to force shutdown after turning it back on after 20mins or so the GPU went back to normal I quickly uninstalled GPU Tweak, fearing that when it automatically launches the settings would make my GPU go black again I then noticed that I lost data in the folder that GPU T was in and the HDD with those files got much slower, I tried launching Steam but it would take almost a minute to launch. Overall I would like to know if there are any major damage or anything that I should know about and is there a way to fix my HDD back to its original speed?
